Moreover, an endless chain 67 is wound between each sprocket 65a-65g and the outside of each guide body 66a, 66b, and a large number of packing bars 68 are provided between a pair of opposed endless chains 67. The plurality of packing bars 68 circulate on the same locus as the endless chain 67 by erection at regular intervals in the circumferential direction.

Furthermore, a large number of packing bars 68 that circulate around the arc-shaped guide bodies 66a, 66b having a large central angle exceeding 180 degrees, and both packing bars 68 facing each other at these packing bars 68. The side plates 61a and 62a of the chambers 61 and 62 form a roll bale forming chamber S.

In the front chamber 61, a twine payout body 69 is arranged, and the twine payout body 69 is provided.
Feeds a twine (not shown) from the twine bundle 70, and spirals the twine around the outer periphery of the roll bale R at the portion of the roller 71 that is in contact with the center of rotation of the roll bale R after molding. The roll bale R is wrapped around to bind the entire roll bale R.

In this manner, the straw h is rearward from the rear transport beater 47 through the straw transport flow path a in a state where the many packing bars 68 forming the peripheral wall of the roll bale molding chamber S are orbiting. While being transported to, the diffusion / guide 48
Are diffused in the left-right width direction and are continuously fed into the roll bale forming chamber S in a throwing state.

In the roll bale forming chamber S, the volume of the straw h is gradually increased by the circulation of a large number of packing bars 68 in the same direction, and finally the roll bale is formed. The room S is filled with straw h.

As a result, in the roll bale forming chamber S,
The roll bale R packed and formed in a roll shape is compressed along both the radial direction and the axial direction to form a strongly compacted roll bale R.

After forming the roll bale R, the twine is wound around the outer periphery of the roll bale R by the twine feeding body 69 to bind it, and then the open / close cylinder is formed.
By opening the rear chamber 62 by 72, the rear end opening 73 of the front chamber 61 is opened, and the roll bale R can be discharged from the rear end opening 73 onto the field scene G.

[0048]

According to the present invention, the following effects can be obtained.

According to the first aspect of the present invention, in a combine having a cutting section, a threshing section, a sorting section and a grain storing section, a roll baler section is connected to the threshing section and discharged from the threshing section. The straw is formed into a roll bale by the roll baler part.

In this way, the grain rod is mowed by the mowing unit, the trimmed culms are threshed by the threshing unit, the threshed grains are sorted by the sorting unit, and the sorted grain is stored in the grain storage unit. At the same time, the straw discharged from the threshing unit can be formed into a roll bale by the roll baler unit.

Therefore, it is possible to continuously perform from the cutting to the straw treatment for forming the roll bale, and the working efficiency can be improved as a whole.

Moreover, since it is not necessary to prepare a roll baler separately from the combine harvester, the cost and storage space for maintaining and managing the machine can be reduced.

According to the second aspect of the present invention, the roll baler unit is attached to the rear portion of the machine body so as to be replaceable with the straw processing unit.

In this way, the straw treating section can be attached in place of the roll baler section if necessary, so that the shredded straw can be scattered in the field.

When performing maintenance on the roll baler unit or the straw processing unit, they can be detached from the machine body, so that they can be easily maintained.
